Environmental impact assessment of hydropower project based on ANP2 FCE model

T here is interaction between each index in the environmental impact assessment system of the hydropower project. An2 alytic network process( ANP) and fuzzy comprehensive evaluation( FCE) were used to perform the comprehensive evaluation of the environmental impact of hydropower project. First, the network structure model for the environmental impact assessment of hydropower project was developed based on ANP and the weights of all evaluation indexes were determined. T his method over2 comes the disadvantage of not reflecting the interaction between the indexes using the analytic hierarchy process( AHP) . T hen, the theory and method of FCE were introduced to perform the environmental impact assessment of hydropower project, and the ANP2FCE model to evaluate environmental impact of hydropower project was proposed. Finally, the model was applied to a hy2 dropower project in north China and the results suggested the evaluation model is reasonable and effective.
